In addition, new energy vehicle charging piles can be installed in underground civil air defense parking spaces, and the protection efficiency of civil air defense projects shall not be affected during installation and use. At the same time, in accordance with the requirements and provisions of the Notice on Accelerating the Construction of Electric Vehicle Charging Infrastructure in Residential Areas and the Technical Standards for Electric Vehicle Decentralized Charging Facilities Engineering, the relevant installation procedures shall be performed.
Second, the civil air defense electromechanical general electric requirements:
1. Lightning protection grounding working grounding: the distribution is indirect, the protective duty room is grounded, and the generator of the power station is grounded.
Protective grounding: machine room grounding, metal conduit, electrical metal conduit, metal bridge (cable bridge) grounding, metal electric door (electric fire shutter door) grounding, and mechanical parking space grounding.
Anti-static grounding: grounding of oil tank, oil pipeline and oil unloading vehicle.
Shielding grounding: grounding of metal door frame, structural steel mesh of emergency rescue project and command project, grounding of oil net dust filter, grounding of embedded pipelines such as wind-proof water and electricity.
Foundation grounding:
1). The grounding resistance of working grounding and weak current grounding is less than 1 ohm.
2) The angle iron of each door frame is welded with 25*4 hot-dip galvanized flat steel on the upper reinforcement of the bottom plate, and the upper reinforcement is at least connected with the welded steel mesh by electric welding.
